How to get the read and write time of a hadoop job?
Hi,
For a hadoop job, I can get its execution time by record the job submission
timestamp and the job end timestamp. However, I would like to know the
breakdown of the execution time, such as the time spent actually on reading
the input files and on writing output files. How can I get the read and
write time?
Thanks,
Yong

Every job has a job-history file which has a lot of stats. You can use 'rumen' to parse them. Rumen is included in every hadoop release.
